Okay soo, kinesis is the directional movement of an organisms whole body towards a stimuli.
So for example, photo (light) kinesis means the movement of the woodlice in response to light.

Positive photo kinesis means the woodlice's whole body moves towards the stimuli which is the light.

This is how i learnt it.

You have 3 words e.g. Positive photo kinesis.
Positive means towards.
Photo means light.
Kinesis means the whole body of the organism.

Sooo... Negative means away. Photo means light.
Kinesis means movement of whole body of organism.

Secondly another reflex is taxis. This is different to kinesis.

Taxis is the random movement of the organism in response to the stimuli.

It has the same naming principal to the kinesis.

Kinesis - directional movement and whole body.

Taxis - non directional

Hope iv explained okayish lol
